'To aller/mmtmay/ concern g e vlie itknown: that I. .hams G. Hannan.' a citizen of the UnitedStates, residingvatlierwick, in the. county oftolumbia and State of Pennsylvania, have invented certain new and useful improvements .in lVrenehes, of which the followingis aspecification.

This invention relates to wrenches and has for its primary object to provide a wrench which is readily disassembled and assembled Another object is to provide a wrench, the working parts of which are inclosed.

A further object is to providelpivoted socket holding members and to provide novelmeans for holding said members against accidental separation.

lVith these 4and other objects in view the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

ln the drawings: Figure 1 is a plan view of the improved wrench; Fig. 2 is an edge view: Fig. 3 is a horizontal sectional view through the head; Fig. 4 is a section on the line 4--4 of Fig. l.

Referring to the drawings by numerals, l designates the handle which is provided at its inner end with an enlarged rectangularl vshape l portion Q ,.lugs 3 being formed on the outer faces of the portion 2 for a purpose which will hereinafter be described. rllhe enlarged portion 2 is bifurcated as will be recognized upon reference to Fig. 4, so as to provide for the reception of an actnating pawl that will be presently described.

A pair of substantially semicireularlyshaped sockets that are provided forholding members 4 and 5 are pivoted together asi/at 6 and their free ends are provided with offsetl extensions 7 and 8, respectively. A channel or groove 9 is formed in each of the members 4 and 5, which is adapted to receive a tongue 10 formed on the circumferential edge of a socket member l1.

In assembling the parts referred to, the socket 11 is first arranged between the memi bers 4 and 5, after which the sleeve 13 is moved into place about the extensions 7 and S. lYhien the sleeve 13 assumes this position -the `'sf ,ket 1l will be securely retained in revoluble relation to the members 4 and 5. The enlargement Q on the handle l is now brought .into positionubetween the extensions Specification of Letters Patent.

7 and 8 so that the lugs 3 bear against the sleeve soas to retain. the latter in -a rigic the,` handle in a firmvr position. Then the'f' parts assume this position the pawl .14' will" be y-ieldingly held in engagement with certain of the notches 15 in the socket. Consequently when thehandle l is oscillated the pawl will cause the rotation of the socket in a desired manner.

A pawl 14 is slidably arranged between the extensions T and .8 and the bifurcated end of the portion 2. This pawl is normally held in engagement with notches 15, formed in the edge of the socket 11, by means of a coil spring 16 which bears against the inne-n1v face of the pawl 14 and handle l. An opening 17 is formed in the socket 11 `to receive the heads of bolts or nuts to be turned. It will be seen that by engaging the socket 11 with a bolt and exerting pressure upon the handle l, the socket 11 will becaused to rotate by means of the pawl 14. Also that the parts of the wrench are easily assembled, or disassembled. If desii-ed. the handle l may be cored as shown at 1S to lessen the weight thereof. Also, if desiredgoil or any other suitable lubricant may be placed in thisboreto supply a lubricant to the working part-s of the wrench.

From the foregoing description taken in connection with the accompanying drawings it is thought that the construction and operation of the device will be clearly understood and while l have herein shown and described one speciiic form "of my invention .I do not wish to be limited thereto, except ment with said socket` a handle portion, an

enlargement on one end 'of said handle portion, said enlargement extending between lOG Said'- l "ineens, connecting said' 'en-ij -Iargfementffand said extensions,r a. pair of 'of' the bivfrc'atio'n: injsa'id; enlarged portion, and af ring to retainsaid pawl in engagement lwitlrseid socket, as and 'for 'the purpose-set forth andde'scribeif wrenc of. the character described comprising e ipeir.. of substantially semicrcular holdng'members,onefend of said'V -mmbers being pivotally connected together,A .extensions formed at'the freeends 'offsaid' fmembers and extending in substantially par- VMiel-relation.toeech' other, a socket arranged 'between s"aid i members,A a.' sleeve :mesme mounted on said extensions to retain said members inengagement with said'socket, a ze hndle' poration hauling` an enlargementl fiormed et one end, said enlargement fitting In testimony whereof I-aiix my signture 8o in presence of two witneses.. l
